摘要

A tray loading system for tested electronic components including a tray loading bin adapted to prevent trays of a first configuration from being operably received in a first bin operating mode and to operably receive trays of the first configuration in a second bin operating mode. The system also includes an operating mode switching assembly adapted to automatically change from the second operating mode to the first operating mode in response to an operation associated with removal of loaded trays of the first configuration from the tray loading bin.
